Forget about Okposo and just concentrate on the possiblity that one of these guys will make at least a decent 3rd line winger. That is what we need to replace Okposo because that is what he is.
A development program is just that......developing quality prospects that have the potential to succeed. Not all will make it, not all will pan out where projected, but it appears that we have enough young prospects with ability to feel at least one of them will be able to replace an inconsistant, limited 3rd liner.

When one of those AHL, KHL or college players actually makes the NYI roster, they can then take Okposo's spot and then Okposo will be moved.
